The first kit is strictly DNA testing. It’ll tell you all about your family’s history, your ethnic background, and maybe reveal some interesting facts about yourself you never knew. You’ll also be able to connect with relatives based on your DNA from all around the world. If you want to, you’ll be able to upgrade to the health screening later but it will cost extra. The second, more expensive option is the one that adds health screening. It will tell you everything your DNA tells them about your health, your traits, and what you might be at risk for.
